I had the same problem. It had to do with the initialization string for my
modem. I went into windows and looked at the modem log file and saw what
string(s) my driver was giving the modem. I put these in and it's working
great, now. Your next thing will be making sure you read the posts about the
.options file in this newsgroup.


(part 2)

Control Panel - Modem - Properties (of modem, not a winmodem) - connection,
hit advanced button, hit view log.
In this file are usually 2 init strings. You have to put them together into
one for linux. Here's what mine looked like with 2 and here's what I did to
put them together for linux.

Recv: AT &F &C1  S95=47 W2 S0=0<cr>
Recv: ATS7=60S30=0L0M0\N4%C3&K3B0N1X3<cr>
The combined at init command:
at&f&c1s95=47w2s0=0s7=60s30=0\n4%cc3&k3b0n1x3
notice that I skipped the l0m0 because kppp will actually send these speaker
volume commands to your modem after you initialize it.

You must also cp .options .options.old then touch .options
I actually didn't do this. I created a new .options file after I backed up
the old one and then added one line to the bottom "noauth".
I works great now.
